まれていた。[Prior Art] Cyclodextrins form structure-specific inclusion compounds with various guest compounds in aqueous solutions. Therefore, solid membranes containing cyclodextrin are expected to have specific separation ability and permeability, and by supporting cyclodextrin on polymers, various physical properties that could not be achieved as a single substance are expected. Since this method can be used to expand the range of applications, there has been a desire for a method that can freely create membranes containing cyclodextrin.

されている。Regarding the preparation of such a cyclodextrin membrane, for example, Japanese Patent Application Laid-Open No. 60-232210 discloses that a polymer consisting of crystals of a cyclodextrin clathrate compound and a compound having an isocyanate group is cast onto a commercially available ultrafiltration membrane. A method for
Publication No. 702 discloses a method of forming a film using a known method from a polymer obtained by reacting cyclodextrin with various monomers and then copolymerizing it with an acrylonitrile derivative.

The method disclosed in No. 02 was not sufficient because the rate of cyclodextrin introduction into the resulting polymer membrane was low.

It has been found that this can be achieved by a method for producing a cyclodextrin membrane, which is characterized by spreading a solution obtained by dissolving it on a support and then drying it.
